Weather in September
Temperature
September's onset brings an average high-temperature of a still hot 31.3°C (88.3°F), showing a minute difference from August's 30.6°C (87.1°F). Srengsem's average low-temperature in September is measured at an agreeable 22.4°C (72.3°F).Heat index
The heat index value during September is estimated at a blisteringly hot 41°C (105.8°F). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.Bear in mind that the heat index values are determined for shaded areas and light breezes. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. Additional elements including metabolic differences, the level of physical activity, and attire have a role in shaping the individual's temperature perception. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
